E1/A-law
T1/μ-law
T1/μ-law
Specifies the type of interface that is between the trunk and Blueworx Voice Response. The choice of interface type also affects the voice encoding scheme that is used. A-law and μ-law are the voice encoding schemes normally used by E1 and T1 interfaces respectively. However, it is possible to use A-law encoding with a T1 interface; to do so, set the Switch Encoding Law parameter to A-law.
